DG140 Series

DC EC

Applications

For high-efficiency ventilation in a North American residential heat recovery ventilator (HRV) where low noise and energy savings are critical, the DG140A-E072A1-01 (EC, 115 V AC, 380 m³/h, 60 W) is suitable for its electronically commutated motor that delivers precise speed control and reduced power consumption. For a European commercial kitchen extract system operating on standard mains power, the DG140A-E072A3-01 (EC, 230 V AC, 380 m³/h, 60 W) is suitable for its ability to handle continuous grease-laden airflow with low maintenance and high reliability. For a North American data center’s hot-aisle containment exhaust, the DG140B-E072D1-01 (EC, 115 V AC, 460 m³/h, 100 W) is suitable for its higher airflow and robust EC motor that maintains stable performance under varying static pressure. For a European industrial drying oven’s recirculation fan, the DG140B-E072D3-01 (EC, 230 V AC, 460 m³/h, 100 W) is suitable for its high-temperature tolerance and efficient operation at 230 V AC. For a solar-powered off-grid telecom cabinet cooling system, the DG140A-D092A0-01 (DC, 310 V DC, 430 m³/h, 100 W) is suitable for its direct high-voltage DC operation that eliminates the need for an inverter, maximizing energy efficiency. For a 24 V DC battery room ventilation system in a North American forklift charging station, the DG140A-D072A6-01 (DC, 24 V DC, 430 m³/h, 60 W) is suitable for its low-voltage DC design that safely vents hydrogen gas while drawing minimal power from the battery bank.

FAQ

DG140A-D072A6-01

How noisy is the DG140 series?

Rated noise across the DG140 series spans 59–66 dB(A) depending on model and size. Because noise follows speed, the easiest way to reduce sound levels is to choose a smaller model at a lower speed for the same airflow, or a speed-controlled EC/DC version where available — ideal for noise-sensitive environments such as offices, laboratories and residential ventilation.

What bearings do DG140 fans use, and how long do they last?

Models in the DG140 series use NSK ball bearings, which supports continuous-duty operation in HVAC and industrial ventilation. Bearing life depends mainly on operating speed and temperature: keeping inlet air clean, avoiding vibration and running at moderate speeds maximise service life. For an L10 life estimate at your exact operating point, contact our engineering team.

Are DG140 fans suitable for dusty or outdoor environments?

Protection classes in the DG140 series include IP44. Models rated IP44 seal the motor against dust and splashing water for typical industrial environments; for outdoor or wash-down installations, choose the highest IP rating available in the series and avoid direct high-pressure water jets. The standard operating temperature range is -25 °C ~ +60 °C.

How do I choose the right DG140 model?

Start from the airflow you need — the DG140 series covers 380–460 m³/h. In this series, DC models suit battery- and solar-powered systems. EC models offer stepless speed control and the best efficiency at partial load. The comparison table on this page lists airflow, voltage, power and noise for every model, or send us your operating point (airflow and static pressure) and our engineers will size the right model for you.

What is the MOQ, lead time and sampling policy for DG140 fans?

Standard MOQ is 270 PCS per model, with a typical lead time of 25-30 days. Samples are available for evaluation before volume orders. OEM/ODM customization — private labels, connectors and speed curves — is supported at our Foshan factory.
